Product & Service Introduction:
===============================
Email Protection is a powerful perimeter email anti-malware product. It fights spam, viruses, zombies 
and phishing attacks, provides realtime updates and powerful reporting capabilities that help prevent 
email threats from reaching your computers, thus reducing costs and increasing productivity.
The web content filter helps ensure that employees access only those resources that help them accomplish 
work related activities. Access to time wasting social networks like Twitter and Facebook can be restricted 
or completely eliminated. Internet crime is at an all-time high. There are thousands of sites that try to 
steal credit card information or install viruses and spyware programs on your computer. Sadly, at the rate 
that they are appearing, anything less than a fully automated solution won’t catch them. By blocking malware 
websites using Web Protection, you make sure nobody will ever access them, and lower the risk for data 
and financial losses. Legislation makes it the company’s responsibility to ensure a safe environment for the 
employees. That includes restricting access to potentially illegal resources and websites. The Application 
Filter can block downloads from P2P networks (torrents, aMule etc.) or via Instant Messengers. A lot of similar 
products are built by highly technical engineers and as such, lack attention to regular users who a lot of 
times are frustrated by seemingly impossible configuration interfaces. Our development philosophy emphasizes 
ease of use, so we spend a lot of time doing usability studies that help us create easy to use, yet powerful 
products. Configuring and deploying such a product can be a real challenge in more complex environments. We 
offer professional technical support to all our customers, thus making sure they get from zero to a fully 
functioning installation in the shortest time possible. Each business is unique and so is their I.T. infrastructure. 
Our customers demand ease of integration into existing networks. Web Protection can be deployed in a variety 
of scenarios, thanks to its ability to come in several versions (hardware, software and virtualized).
